Hopefully this is the right forum for my question.
I’ve been sharing my faith to family/friends when the right opportunity arises but it has been difficult because they sometimes ask difficult questions I’m not always prepared to answer. In order to prepare, I have been reading a few Apologetics books. The problem is – they are long and detailed. The books are extremely informative, but is there a summary somewhere of the key Christian beliefs, along with the criticisms/difficult questions, with effective answers to them?
I could keep this type of summary with me to refer to when I get an unexpected opportunity to share my faith with non-believers.
